I have a 2001 Audi A3 1.8T FWD 8L and the speedo went dead. I got it hooked up on an OBD scan tool(no access to a VAG-Com at the moment) and it says "implausible signal".
I purchased a new unit from ECS tuning and fitted them myself. I was surprised to find out the speedometer's still not functioning. Error code remains the same.
Any clues to this problem?
